To all whom it may concern:

Be it known that I, EMIL PRAZAK, a citizen 'of the United States, and resident of Eliza both, in the county of Union and State of New Jersey, have invented certain new and useful Attachments for Talking-Machines, of which the following is a specification.

This invention relates to talking machines and more particularly to means by which the two common t es of these machines, namely; the mac e employin a cylindrical record and that using the isk record, may be combinediwith little cost, simplicity of arrangement and almost instantly and a common motor used to rotate either record.

The device comprises a franie with arotating platform mounted onroller bearings and having pulleys'carrying a belt or gearing.

driven by the motor of a cylinder record machine as will be more fully described in the following specification, set forth in the claims and shown in thedrawings where it will be seen that like reference characters are used to designate the same parts in theseveral.

Figure 1 is a perspective v1ew of a phonograph. Fig. 2 is a side elevation of the device detached. Fig. 3 is a plan view ofsam'e.

The device is adaptedito be'carried by the center of the arbor 5 and the guide'rod 6 of the ordinary phonograph and extensions of these two parts enter the holes 7 and 8 rea disk operating talking machine or to combine the operation of the two records and cause them to work simultaneously. 7

Theframe 9 as will be seen'rn Figs. 2 and 3 has at one end a bracket 10 sup orting on ball bearings 11 the 1 circular pl atform 12 while the latters shaft 13 is journaled in the forked arms ofthe bracket and carries a pulley 14 by whichthe platform is rotated, The

other end of the franie carries an arm 1;5 with p I plate for. the record, a. reproducer, an am- The frame 9 has secured to it a bracket 20 in which are journaled the pulleys 21 and 22 and which direct the band 23 from themotor a socket 16 and pivot 17 for the horn.19.

within the box of the phonogra h to the pulley 14. The motor being of t 'e usual construction it has not been thought necessary to show same, but it is obvious that a train of gearing might be substituted, the band is, however, light and noiseless and readily put instrument is ready for operation.

,in place when the attachment is secured to the honograph.

on it is desired to apply my improved device to the phonograph it is simply slipped over the extensions of the arbor center and guide rod and after the belt is adjusted the In case the motor is provided with two driving pulleys the band 24 for the phonograph need not be disturbed'but whichever instrument it is desired to put out of operation its hand is disconnected.

It is obvious that I do not limit myself to exact arrangement of parts and if found advisable or desirable various modifications may be resorted to without departing from the essential features shown and described.

WVhat I claim as new and desire to secure by Letters Patent is:

1. In an attachment for talking machines, thecombination with the arbor center and guide rod of aphonograph, of a frame with perforations adapted to fit the ends of the pulley onthe shaft of the disk and means connected with the motorof the phonograph for driving the pulley.

2. In an attachment the combination with a phonograph, of an arbor center, a guide rod, extensions on the arbor and guide rod,a frame adapted to be secured to said extension and braced against the adjacent sidegof-the phonograph, a rotatingplate adapted to carry disk records, a reproducer and an amplifying horn carried the rotating plate.

3. In. an attachment for talking machines, 'thecombination with a phonograph having an arbor and a guide rod, of extensions to to be carried by the extensions, a'rotating plifying horn, a pulley on the shaft of the plate, a belt connecting the pulley of the motor of the phonograph, and idlers for directing the passage-of the belt.

4:. In an attachme'ntfor talking machines, the combination with a phonograph having to be carried by the arbor and guide rod, a rotating plate for a disl-t record, a ball bearthe exact construction shown nor to thesaid arbor'and guide rod, a rotating'disk, a
